Use complete sentences to describe why Set A = { X | X is an even whole number between 0 and 2} = ∅
Consider the Set A = {X | X is an even whole number between 0 and 2 } = [tex]\Phi[/tex].
Since, whole numbers are the set of numbers starting from zero upto infinity.
Even numbers are the numbers which are exactly divisible by '2'.
So, we have to find the even whole number between 0 and 2.
Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.
Therefore, there is no even whole number between 0 and 2.
So, this set is empty.
Therefore, A = { X | X is an even whole number between 0 and 2} = [tex]\Phi[/tex]

0.075 m = _____ cm
0.075 m is 7.5 centimeters.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement.
Given that, convert 0.075 m into cm
We know that, 1 meter = 100 centimeters
0.075 meter = [(100) × 0.075] centimeter
0.075 meter = (100 × 0.075) centimeter
= (100 × 75/1000) centimeter
= (7500/1000) centimeter
= (75/10) centimeter
= 7.5 centimeter.
Hence, 0.075 m is 7.5 centimeters.

A cab charges $1.45 for the flat fee and $0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has $35 to spend.
$1.45 + $0.55x ≥ $35;Answer:
The correct option is: $1.45 + $0.55x ≤ $35 ; x ≤ 61 miles
Step-by-step explanation:
Suppose, the number of miles Ariel can travel [tex]=x[/tex]
The cab charges $1.45 for the flat fee and $0.55 for each mile. So, the total charges for [tex]x[/tex] miles [tex]=\$1.45+\$0.55x[/tex]
Given that, she has $35 to spend. That means, the total charges must be less than or equal to $35.
So, the inequality will be: [tex]\$1.45+\$0.55x\leq \$35[/tex]
Solving the above inequality....
[tex]1.45+0.55x\leq 35\\ \\ 0.55x\leq 35-1.45\\ \\ 0.55x\leq 33.55\\ \\ x\leq \frac{33.55}{0.55}\\ \\ x\leq 61[/tex]
So, the number of miles Ariel can travel is 61 miles.

If h and k are constants and x^2+kx+7 is equivalent to (x+1)(x+h), what is the value of k?
To find the value of k when x^2+kx+7 is equivalent to (x+1)(x+h), we expand (x+1)(x+h), compare coefficients, and deduce that k is 8.
Explanation:If h and k are constants and x^2+kx+7 is equivalent to (x+1)(x+h), we are looking for the value of k. To find k, we expand the right-hand side and then compare coefficients.
Expanding (x+1)(x+h) gives us x^2+hx+x+h, which simplifies to x^2+(h+1)x+h.
Comparing this to x^2+kx+7, we can see that k must be equal to h+1.
Since there is no h term in x^2+kx+7, we infer that h must be equal to 7. Consequently, k=h+1 which leads us to k=7+1.
Therefore, the value of k is 8.

Item 15 The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone. The formula for the surface area S of a right cone is S=πr2+πrl,S=πr2+πrl, where r is the radius of the base and l is the slant height. Find the height of the cone.
Final answer:
The height of the cone is equal to the slant height plus 1.
Explanation:
To find the height of the cone, we can use the formula for the surface area of a cone: S = πr^2 + πrl, where r is the radius of the base and l is the slant height. Since the problem states that the surface area is equal to the volume, we can set S equal to V and solve for h, the height of the cone.
Here's the step-by-step calculation:
S = V
πr² + πrl = V
πr² + πrl = πr²h
πr² + πrl - πr²h = 0
Combine like terms: πr²(1 - h) + πrl = 0
Divide both sides by πr to solve for h: 1 - h + l = 0
Subtract l from both sides: 1 - h = -l
Subtract 1 from both sides: -h = -l - 1
Multiply both sides by -1 to solve for h: h = l + 1
So, the height of the cone is h = l + 1.

A commuter plane provides transportation from an international airport to the surrounding cities. one commuter plane averaged 280 mph flying to a city and 120 mph returning to the international airport. the total flying time was 3 h. find the distance between the two airports.
The distance between the two airports is 252 miles
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance between the two airports be = D
Now ,
Let the first airport be = A
Let the second airport be = B
And , the speed from Airport A to Airport B averaged = 280 mph
The speed from Airport B to Airport A averaged = 120 mph
The total time taken for the journey = 3 hours
So , the value of Time T = 3 hours
So , the equation will be
Time = Distance / Speed
Since , the distance between the airports remains the same on the journey,
Time = D/280 + D / 120
Substituting the values in the equation, we get
D/280 + D / 120 = 3
The LCM of 280 and 120 is 840 , so
( 3D + 7D ) / 840 = 3
On simplifying the equation , we get
Multiply by 840 on both sides of the equation , we get
10D = 2520
Divide by 10 on both sides of the equation , we get
D = 252 miles
Therefore , the value of distance D from the equation is 252 miles
Hence , The distance between the two airports is 252 miles

Final answer:
By solving the equation 280t = 120(3 - t), we find that the time taken to fly to the city is 0.9 hours. Multiplying this by the speed of 280 mph, the distance between the two airports is determined to be 252 miles.
Explanation:
To find the distance between the two airports, we can use the formula distance = speed × time, but first, we need to find the time taken for each leg of the journey. Let t be the time (in hours) it takes for the plane to fly to the city at 280 mph. Hence, the time taken to return to the international airport at 120 mph will be 3 - t hours. We can establish the following equations based on this information:
To the city: 280t (since distance = 280 mph × t)
Returning: 120(3 - t) (since distance = 120 mph × (3 - t))
Since the distances are equal for both trips, we can set the equations equal to each other:
280t = 120(3 - t)
Solving for t, we get:
280t = 360 - 120t
400t = 360
t = 0.9
The time taken to fly to the city at 280 mph is 0.9 hours. Now we can find the distance:
Distance to the city = 280 mph × 0.9 h = 252 miles.
Therefore, the distance between the two airports is 252 miles.
